Question:
Which one of the following protocols may need to broadcast some of its messages?
Which one of the following protocols may need to broadcast some of its messages?
Show Hint
Think about which protocol's client does not yet have an IP address and therefore cannot address a specific server directly, so it must broadcast.
Updated On: Jul 7, 2026
- SMTP
- FTP
- DHCP
- HTTP
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Examine each protocol's addressing requirement.
Step 2: SMTP, FTP and HTTP are application layer protocols that operate between a client and a server whose IP address is already known, either resolved via DNS or already configured, so they only need unicast communication.
Step 3: DHCP is used by a host to obtain an IP address when it has no IP address yet. Since the host does not know the address of the DHCP server, it sends a DHCPDISCOVER message as a broadcast, destination 255.255.255.255, so that any DHCP server on the local network can respond.
Final Answer: DHCP (Option C)

- Suppose a program is running on a non-pipelined single processor computer system. The computer is connected to an external device that can interrupt the processor asynchronously. The processor needs to execute the interrupt service routine (ISR) to serve this interrupt. The following steps (not necessarily in order) are taken by the processor when the interrupt arrives:
(i) The processor saves the content of the program counter.
(ii) The program counter is loaded with the start address of the ISR.
(iii) The processor finishes the present instruction.
